My displacement maps do not work in Vray + Maya and I have no idea why.

Tried V-ray 2.2 and 2.4. No difference between mudbox, zbrush

Using 32-bit open exr.

I've read every single resource I could find on the internet and none have the answer. Really getting stuck here.

It has nothing to do with gamma, allow negative colors, displacement amount or shift, .. or anything, really. There is no logical reason why my displacement maps come out with a lack of detail in areas. And I've read almost every thread here, all of them just say to allow negative colors and the thread concludes, but that does not work.

I'll just upload the scene, probably easiest way to get help, hopefully someone can figure this out.

My guess is it's a combination of things that are working against me in tandem and I need to get specific settings right. But I've done a lot of tutorials on it without luck.

I usually eye-balled displacement amount. For this one I only set it to 10 so its easier to see.

I did a little check and found out your displacement only has values in R channel. You'll need to tick the "alpha is luminance" check box in your texture node in this case. 2013 has it checked by default I think

I'm still having issues. That one wall came out fine but everything else I do is still missing critical details.

I don't get it at all. Why wont they work I know I'm doing it right

Here's a new scene file where they do not work right either. Could you or someone give this a render and see if it works? If it works it means something might be wrong with my installs or something. I know it's not my prefs.

Not sure if you resolved this or not but I know there was a known bug with the VrayDisplacement node where you would actually have to drag and drop the texture into the node rather than hitting the little checker button in the attribute editor.
